Hacker News Plugin

A hyper-mcp plugin that fetches the top stories from Hacker News (max 100 stories).

This plugin connects to the Hacker News API to fetch the current top stories and display them with their titles, scores, authors, and URLs.

Usage

Add the plugin to your hyper-mcp configuration: can be oci://ghcr.io/hungran/hyper-mcp-hackernews-tool.wasm or wasi path file plugin.wasm

{
  "plugins": [
    {
      "name": "hackernews",
      "path": "oci://ghcr.io/hungran/hyper-mcp-hackernews-tool:latest",
      "runtime_config": {
        "allowed_host": "hacker-news.firebaseio.com"
      }
    }
  ]
}

The allowed_host configuration must include * or specifically hacker-news.firebaseio.com to allow API requests.

Building

To build the plugin:

# Make sure build.sh is executable
chmod +x build.sh

# Run the build script
./build.sh

This will create a plugin.wasm file that can be referenced in your hyper-mcp configuration.

API

The plugin requires a simple dummy parameter:

{
  "random_string": "any_value"
}

From the terminal:

echo '{ "jsonrpc": "2.0", "id": 1, "method": "tools/call", "params": { "name": "hackernews", "arguments": { "random_string": "dummy" } } }' | hyper-mcp
